CLEAN: Sirens wail across Israel in huge defence drill

Air raid sirens wailed across Israel on Wednesday at the peak of a five-day civil defence exercise to test the Jewish state's defences in the event of war, the army said. The sirens sounded at 11:00 am (0800 GMT) for 90 seconds, sending civilians across the country into their nearest bomb shelter or protected space where they waited for 10 minutes until the all-clear.
